Application led November 23, 1908.

To all whom it may concern:

Be it known that I, HENRY C. Gawnnr., a

securely mounted sprockets 8, connected by citizen of the United States,residing at (,hi-

cago, in the county of (look and State of I Illinois, have inventedcertain new and useful Improvements 1n Blue-Print Yt'vashers, of whichthe following is a specification.

My invention relates to blue print washin their path of movementactuated by the ers, and the object thereofis to provide a simple andinexpensive apparatus for washing prints, which will wet the printedside of the paper only.

In the accompanying drawing illustrating my invention, and forming a'vpart of this i specification, Figure l is a transverse verticalsectional view taken through my Vimproved device, and, Fig. 2 is a'longitudinal vertical sectional View taken through the same.

In the practical embodiment of my invention, I provide an elongatedrelatively narrow tank 1provided with vertical slots 2 in its ends, andextending for a short distance from the upper edge thereof. Ars rangedlongitudinally within the tank 1, adjacent the upper edges thereof, andin paral- 'lel relation upon each side of its said slots 2, areperforated pipes 3, to which an inlet pipe 4 is lead, to supply' thesame with the washing fluid, said pipes being so arranged as to spraythe said washing fluid downwardly and toward one another. The supportingrod 5 is adapted for insertion longitudinally of the tank l, betweensaid perforated pipes 3, and engaging within and resting upon the baseof said tank slots 2, said rod 5 being of substantially greater lengththan the `said tank, whereby the ends thereof project outwardly beyondsaid tank slots 2, and form handles whereby the saine may be readilyplaced within, and removed from the said tank. The supporting rod 5 isadapted to receive a print A centrally folded thereover, and hungthereon with its printed surface outermost, to be exposed to the sprayfrom the perforated pipes 5l, when said snpporting rod is inserted inposition shown in the drawings.`

In order to readily manipulate the insertion and removal of the printsupporting rod 5, I may provide a shaft t5 jou'rnaled through brackets 7upon one .side of the tank .1,'adja- BLUE-PRINT WASHER.

shaft t3 beyond the ends of saidtank l, aref' sprocket chains t), to thesprocket wheels 1l mounted upon a parallel shaft l0, suitably Ijournaled above said shaft 6,-whieh chains t) are provided withsemicircular cups 12, equid'istantly spaced thereon and adapted rotationof either of said shafts 6 or 10, to

engage the'outwardly projecting ends of the print supporting rods 5, asshown in Fig. 2. Thus by the movement of the sprocket chains l), a printsupporting rod may be raised upwardly from the tank l, and after its removal from saidpchains, another rod carrying a fresh printed sheet, maybe placedy in connection therewith, and lowered into said tankbyr'everse rotation of said Chains.

-l provide the tank l with av discharge cock or faucet 13,at the basethereof, in order to prevent the same from retaining the washing liquidthrown therein from pipes 3.

ljlaving fully'described my invention, I clalm:

l. In a blueprint washer, the combination of a tank, parallel perforatedpipes arranged therein, to spra'y a liquid toward one another, and aprint holding member supported between said pipes and adapted for thereception of a print centrally folded thercover, and hung thereon withits printed surface outern'iost, and exposed to the said liquid spray,substantially as described.

ln a blue print washer, the combination ol' a tank, provided with anoutlet at the base thereof, parallel perforated pipes arranged thereinto spray a liquid toward one a1?- other,"a print holding rod adapted forthe reception of a print centrally folded thereover, its printed surfaceoutermost, and means` carried by said tank for supporting said rodtherein, between said perforated pipes,substantially' as described.

il. ln a blue print washer, the combination of a tank having an outletat the base thereof, and provided with vertical slots in its ends at theupper edges thereof, parallel perforated pipes arranged within saidtank, extending between the ends thereof at each side of said slots, tospray a liquid toward one another,.a print holding member snpported-Within said tank slots, and having its ends projecting beyond the same,and adapted for the yreception of the print centrally folded t-hereoverand hung thereon withv its printed surface outermost and exposed to theSaid liquid spray, substantially as described.
